public class Main 

{/* from n o w j a v a . c o m - 时代Java*/

   public static void main(String[] args)

   {

      // create Scanner to obtain input from command window

      Scanner input = new Scanner(System.in);


      int x; // first number input by user

      int y; // second number input by user

      int z; // third number input by user

      int result; // product of numbers


      System.out.print("Enter first integer: "); // prompt for input

      x = input.nextInt(); // read first integer


      System.out.print("Enter second integer: "); // prompt for input

      y = input.nextInt(); // read second integer

      

      System.out.print("Enter third integer: "); // prompt for input

      z = input.nextInt(
